PowerVR Series5XT

The PowerVR SGX544 Series5XT Graphics Processing Unit (GPU) IP core is a highly efficient graphics acceleration IP core that meets the multimedia requirements of the next generation of automotive, consumer, communications and computing applications. PowerVR SGX Series5XT architecture is fully scalable for a wide range of area and performance requirements, enabling it to target markets from low cost feature-rich mobile multimedia products to very high performance consoles and computing devices. The family incorporates the second-generation Universal Scalable Shader Engine (USSE2™), with a feature set that exceeds the requirements of OpenGL 2.0 and Microsoft Shader Model 3, enabling 2D, 3D and general purpose (GP-GPU) processing in a single core.

Comprehensive Roadmap

Programmable USSE2

USSE2 is a scalable multi-threaded multimedia processing engine offering up to 2x the floating point throughput of earlier Series5 vector operations and co-issue capabilities enables advanced geometry and pixel processing as well as GP-GPU tasks. These tasks are broken down into processing packets which are then scheduled across a number of multi-threaded execution units in the USSE2.


This enables optimal hardware load balancing, maximum latency tolerance and efficient gate use, all accessed through a single software programming model and compiler. For maximum efficiency, additional optimized hardware engines, including texture, pixel and tiling accelerators work with USSE2 in the PowerVR SGX Series5XT architecture to deliver even higher anti-aliasing performance. 


USSE2 enables up to IEEE 754 single precision floating point data processing – essential for the best possible image quality and vital for effective GP-GPU multimedia processing. An advanced microkernel based approach to scheduling ensures maximum performance with minimal CPU load and enables extremely rapid context switching and concurrent multi-API support.

YUV, Colour Space Accelerators & S3D Support

The USSE2 workload is reduced by the addition of dedicated YUV and Colour Space Accelerators for optimal interaction with video cores (e.g., PowerVR VXD). Additionally all SGX cores offer immersive support for Stereoscopic 3D (S3D) display enabling all standard modes with minimal overhead.

System Level Cache Option

A range of pre-verified system level cache configurations (32, 64 and 128KB) are available to further reduce bandwidth usage and maximize latency tolerance through access profile optimized caching.

Series5XT Shader-driven TBDR Architecture

Unique, patented tiling technology surface removal (pixel perfect and double the rate of PowerVR Series5. Unlike early Z hierarchical systems used by competing solutions PowerVR offers high performance hidden surface removal irrespective of submission order or primitive orientation resulting in the highest performance hidden surface removal and stencil operation in the industry. 


The family further extends the bandwidth and power efficiency and performance of hardware-based perfect tiling and culling algorithms, which used in combination with seamless scene complexity management and compression, enable PowerVR SGX to handle arbitrarily complex scenes in limited memory footprints with the lowest memory bandwidth usage.

Multi-processor Support

Members of the PowerVR SGX Series5XT family offer Multi- Processor (MP) support for 2 to 16 cores (SGX543, SGX544 and SGX554), enabling complete linear scaling of all GPU performance components (Vertex, Pixel, Setup and GP-GPU) with virtually no overhead in bandwidth usage.

Low Power

PowerVR SGX Series5XT cores are built on a foundation of unique patented technologies that deliver class leading performance while keeping power dissipation to a minimum. PowerVR’s inherently low-power architecture is complemented by the use of the latest sophisticated clock gating techniques to ensure the lowest active and standby power consumption.

High Performance per mW

PowerVR SGX Series5XT core architecture currently comprises SGX543, SGX544 and SGX554 and their respective MP variants covering a wide range of area, feature and performance requirements to accommodate the needs of many target markets. Performance scales with clock speeds from 100 MHz to 400 MHz and beyond.

An extensive ecosystem of tools and support

PowerVR GPU technology is driven by one of the world’s largest engineering teams dedicated to graphics processor development. It is complemented by Imagination’s PowerVR Insider ecosystem, which provides extensive support and tools to an extensive and vibrant community of developers, who have already created hundreds of thousands of apps optimised for PowerVR powered devices.
